Providing contextual information for spoken information

ABSTRACT

Techniques are described for providing relevant information to users (e.g., information that is at least potentially of interest to the users). Relevant information for a user may be automatically determined based on a determined context of the user and/or on a request for that information from the user. For example, voice-based information may be obtained from a user in one or more ways, and then analyzed to identify requests or other indications of information of interest and/or to otherwise determine a context of the user that corresponds to potential information of interest. Relevant information for a user may be provided to the user in various ways, such as via a voice-based response during a telephone call and/or via one or more electronic messages sent to the user (e.g., via emails, instant messages, paging messages, SMS or other text messages, etc.).

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of provisional U.S. Patent Application No. 60/822,910 (Attorney Docket # 81132-3), filed Aug. 18, 2006 and entitled “Contextual Voice Based Advertising System And Method,” which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The following disclosure relates generally to techniques for providing contextually relevant information based on spoken information, such as to provide promotional information to users of a voice-based messaging system.

BACKGROUND

While people are increasingly using data retrieval capabilities of computing devices to access information of a variety of types, voice-based functionality of telephones continues to be commonly used for a variety of purposes, including to obtain information of various types. For example, telephones are frequently used to obtain address and telephone number information for designated individuals or businesses, such as via automated and/or manual directory assistance services. In addition, enhanced directory assistance services exist to provide a variety of types of additional information to telephone users, such as movie listings, weather reports, sports scores, traffic reports, etc. Moreover, some businesses may provide automated telephone systems to provide various information to customers and/or partners about their businesses, such as via Interactive Voice Response (“IVR”) systems. Other types of systems may similarly provide a variety of other types of functionality to voice-based telephone users, such as voice message recording and/or forwarding services (e.g., to record a voice message to later be provided to one or more designated recipients), transcription services (e.g., to record voice-based information that will later be manually and/or automatically converted into text), etc. While various services and systems thus exist for telephone users to obtain some types of voice-based information, it is nonetheless often difficult for telephone users to obtain a variety of other types of information of interest in a desired manner.

In addition, it is often difficult for companies and other entities that wish to provide promotional and other types of information to others to do so in an effective manner. For example, while a variety of types of advertising models are known (e.g., via traditional print media; radio; television; billboards; Internet-based banner ads and sponsored links and pop-up ads; location-based services, such as via data services of mobile devices; etc.), all suffer from various known problems, including difficulties in providing information to users that is currently of interest and in a form and/or manner that is desired.

DETAILED DESCRIPTION

Techniques are described for providing information to users that is relevant to the users (e.g., information that is potentially of interest to the users), such as to reflect current contextual situations of the users. In some embodiments, the techniques include automatically determining relevant information for a user based on a determined context of the user, while in other embodiments relevant information for a user may be identified based on a request for or other indication of that information that is obtained from the user. For example, in at least some embodiments, spoken information is obtained from a user in one or more ways, and the spoken voice-based information is analyzed to identify requests or other indications of information of interest and/or to otherwise determine a context of the user that corresponds to potential information of interest. When relevant information for a user is determined, the information may be provided to the user in various ways, such as via a spoken voice-based response (e.g., immediately, such as during a telephone call with the user and in response to a spoken request or other spoken information from the user) and/or via one or more electronic messages sent to the user (e.g., via one or more emails, instant messages, paging messages, SMS or other text messages, etc.). Additional details are included below related to determining relevant information for user and providing relevant information to users. In addition, in at least some embodiments, a Relevant Information Provider (“RIP”) system automatically performs some or all of the described techniques, as described in greater detail below.

Information that is available to be provided to users may be determined and obtained in various ways in various embodiments. In at least some embodiments, businesses and other entities (e.g., providers of products, such as manufacturers, distributors, retailers, etc.) may have information that they desire to provide to appropriate users, such as advertisements or other promotional materials (e.g., coupons, discount or promotional codes, samples, etc.). If so, such entities may provide their promotional information to an embodiment of the RIP system in various ways, such as via an API (“application programming interface”) provided by the RIP system. Entities may further specify particular promotional information and indicate one or more criteria under which that promotional information is to be provided to particular users in at least some embodiments, such as information about the users (e.g., demographic information, location information, etc.), information about one or more times at which the promotional information is to be provided, etc. As one example, an entity may be allowed to specify a particular target expression (e.g., individual words, phrases, sounds, etc.) for a particular group or piece of promotional information, such that the promotional information is to be provided to users who request information about the target expression and/or to users who use the target expression as part of spoken information obtained from the user. Entities who wish to provide promotional information to users may further be charged various fees in various situations, such as a flat fee, or a fee for each that the promotional information is provided to a user (e.g., by allowing an entity to bid on or otherwise specify a price for a target expression, which the entity then pays each time that the promotional information is provided to a user who uses the target expression).

In at least some embodiments, a determination of relevant information for a user is performed based on spoken voice-based information obtained from the user. For example, a user may place a telephone call to an IVR system or other automated voice-based system (e.g., via a cell phone; a landline phone; a satellite phone; a phone that uses one or more computer networks at least in part, such as for Voice Over IP (“VOIP”); etc.), such as to request particular information (e.g., via a provided voice-based request) and/or to provide spoken information that may be used to determine information about a context of the user. The provided spoken information may be analyzed to determine whether particular promotional or other information is likely to be relevant for that spoken information. As one specific example, if an entity has associated particular promotional information with a particular target expression, and the user uses the target expression in the provided spoken information, that promotional information may be determined to be relevant to the user. If the provided spoken information from a user is intended for one or more recipients other than the user (e.g., as a message to those recipients), the determined relevant information may be provided to some or all of the recipients, whether instead of or in addition to the user.

In some embodiments, the RIP system may operate in conjunction with one or more affiliated systems that provide one or more types of voice-based functionality to users (e.g., with third-party systems in exchange for a fee), while in other embodiments the RIP system may itself provide one or more types of voice-based functionality to users. A non-exclusive list of types of voice-based functionality that may be provided in at least some embodiments to users, such as via a telephone call initiated by a user, include the following: the ability to create voice memos or other messages intended for the user and/or one or more other recipients; directory services; and the ability to use a phone call to check for coupons and/or in response to advertising in broadcast and/or user-directed media (e.g., radio, television, newspapers, magazines, billboards, online information, etc., whether local or regional/national). In some embodiments, the voice-based functionality may be available only to users who have a predefined relationship with the RIP system and/or an affiliated system, such as registered subscriber or member users who have created an account and provided one or more of various types of information about themselves (e.g., a user name; an actual name; a password; electronic message address information for the user, such as an email address, instant message address, fax number, paging number, and/or telephone number for SMS or other text messages; other contact information; demographic information; information about one or more user phone numbers from which the user will contact the RIP system and/or affiliated system; etc.), as well as in some embodiments paying a fee. In other embodiments, the voice-based functionality may be available to all users. In addition, the RIP system and/or affiliated system may provide one or more telephone numbers that users may call to receive the voice-based functionality, such as toll-free numbers that provide information to the RIP system and/or affiliated system about a calling user's telephone number and/or other caller ID information.

The RIP system may provide relevant information to users in various ways. For example, the information may be provided in voice form in some embodiments, such as during a telephone call made by the user that initiates the providing of the relevant information and/or during a later telephone call. In other embodiments, the RIP system may send the information to a telephone caller user in one or more electronic messages, such as if the user is a registered user that has previously provided electronic message address information to be used and the RIP system can identify a telephone caller as a particular registered user (e.g., via use of caller ID or related information that is available about the caller user, via login or other related information explicitly provided by the user, etc.), or if such address information is otherwise available. Furthermore, in some embodiments the RIP system may store the relevant information for later retrieval by a user, such as via a Web site provided by the RIP system.

The use of the described techniques provide various benefits to users who receive relevant information via the RIP system and to entities who make information available to be provided to the users via the RIP system. Non-exclusive examples of some such benefits in at least some embodiments include the following: the ability of users to obtain relevant information for a context of the user; the ability of users to obtain information in a desired form; the ability of users to shield their identity and/or other personal information from advertisers, marketers, businesses and other entities while obtaining requested information or other relevant information related to the entities, such as to request marketing or general information in an anonymous fashion; and the ability of advertisers, marketers, businesses and other entities to target particular information to particular information recipients.

For illustrative purposes, some embodiments are described below in which particular types of information is determined to be relevant for particular types of users in particular ways, and is provided to the users in particular ways. These examples are provided for illustrative purposes and are simplified for the sake of brevity, and the inventive techniques can be used in a wide variety of other situations, some of which are discussed below. For example, in some embodiments, voice-based information may be obtained from users in other manners than via an automated voice system that the users contact, such as by human operators that received the voice-based information from the users and/or in situations in which the users are contacted via telephone. In addition, in some embodiments, information used to determine relevant information for a user is obtained from the user in a form other than voice-based information, such as text-based information.

In at least some of the example scenarios described below, users respond to advertisements in broadcast media, such as for a particular product (e.g., service and/or a physical good) that they would like to know more about (e.g., by obtaining relevant information such as marketing information, product detail, directions, discount coupons, etc.). Furthermore, specific example embodiments of an RIP system are described below with reference to one or more example registered and unregistered users of the RIP system (using example user “Greg” as both a registered user and unregistered user in different example scenarios), although in other embodiments the RIP system may include more and/or less functionality and users may perform other types of actions. In at least some of the examples discussed below, an example embodiment of the RIP system includes a front-end RIP Input Server computing system that interacts with users to obtain voice-based information and a distinct RIP Advertising Database Server computing system that supports the RIP Input Server system to identify particular relevant information for a user based on obtained voice-based information, but in other embodiments the RIP system may be implemented in other manners (e.g., as part of a single computing system).

In the example scenario illustrated in FIG. 1, the caller user is a registered RIP system user whose phone number and email address are previously specified to the RIP system. So, when he calls the example RIP system, it automatically recognizes his phone number and is able to directly deliver a relevant advertising coupon to his email account.

In particular, in this example, Greg listens to or sees an advertisement over the radio or television for a good or service he is interested in, and contacts the RIP system to obtain additional information related to the good/service and/or to the advertisement, although in other embodiments may see such an advertisement via any other mechanism.

Greg dials a phone number provided by the RIP system that could be mentioned in the advertising or otherwise known to Greg (e.g., based on the previous registration process), and says an expression corresponding to the advertisement (e.g., “Larry's Market”), such as an expression that the advertisement indicates to be used during the call. The RIP Input Server recognizes the expression provided by Greg, and informs Greg that he will be sent information corresponding to the advertisement via his registered email address.

The RIP Input Server forwards Greg's message and/or an indication of the recognized expression to the RIP Advertisement Database Server that stores promotional information about Larry's Market.

This promotional information is then forwarded to Greg's email address. In other embodiments, the promotional information may be sent in other manners, such as by sending one or more electronic messages other than emails, and/or by sending related information other than the promotional information (e.g., instructions for accessing the promotional information from another location and/or a user-selectable link to obtain the promotional information). Greg can then take this promotional information (e.g., a discount coupon) to a Larry's Market store in his neighborhood in order to receive a discount or obtain another benefit, or in other embodiments may use the information in other manners (e.g., via an online interaction with a Web site for Larry's Market).

In the example scenario of FIG. 2, the caller user is not a registered RIP system user (or is a registered RIP system user but is calling from a phone that is not previously associated with his account), and thus his phone number and email address are not known by the RIP system or associated with the caller. Accordingly, when the user calls the RIP system, his caller identity information may in at least some situations be obtained, but corresponding electronic message address information is not known for the user unless it is explicitly obtained from the user during the call. Instead, in this example, the relevant information that is requested by or otherwise determined for the user during the call is stored in a specific accessible location, and the caller is informed during the call how to access the stored information. In this example embodiment, the actual relevant information is not shared with the user until he validates that the phone belongs to him, although in other embodiments or situations such validation may not be performed, or other types of validation may be used (e.g., to provide the relevant information to the user only after the user becomes a registered RIP system user).

In particular, in this example, Greg listens to or sees an advertisement over the radio or television for a good or service he is interested in, although in other embodiments may receive such an advertisement via any other mechanism.

Greg dials a phone number provided by the RIP system that could be mentioned in the advertising or otherwise known to Greg, and says an expression corresponding to the advertisement (e.g., “Larry's Market”). The RIP Input Server recognizes the expression provided by Greg, but doesn't recognize Greg as a registered user. Therefore, the RIP Input Server tells Greg to visit a particular part of a Web site provided by the RIP system (e.g., ABCD.com/claim) to retrieve the relevant information, and may further in some embodiments provide additional details regarding how to access the information (e.g., a particular password or code to use to obtain the information). The RIP Input Server may also in some embodiments send a text message to the phone that Greg used for the call to remind him of the location of the information requested, such as in addition to or instead of providing the information in a voice-based manner during the call.

The RIP Input Server forwards Greg's Caller ID and an indication of the recognized expression to the RIP Advertisement Database Server, which stores promotional information about Larry's Market.

In this example, after Greg visits the indicated Web site address (e.g., from a computing system separate from his telephone, or from the same telephone if it provides both voice-based and data-based information retrieval capabilities) and enters the phone number he initially called from, he receives the relevant information (e.g., a discount coupon, such as for use at a physical Larry's Market store in his neighborhood and/or online in order to receive a discount or obtain another benefit). In other embodiments and situations, such as depending on the advertiser's preference, Greg may receive the relevant information only after validating his ownership of this phone or otherwise providing additional information.

In FIG. 3, the caller user is a registered RIP system user, similarly to FIG. 1, but in this example is calling in response to an advertisement in print media (e.g., mass-market print media, such as a newspaper, magazine, etc. that is provided to a city, region, or nation).

In particular, in this example, Greg sees an advertisement in the print media for a good or service he is interested in.

Greg dials a phone number provided by the RIP system that could be mentioned in the advertising or otherwise known to Greg, and says an expression corresponding to the advertisement (e.g., “Larry's Market”), such as an expression that the advertisement indicates to be used during the call. The RIP Input Server recognizes the expression provided by Greg, and informs Greg that he will be sent information corresponding to the advertisement to his registered email address.

In a manner similar to that of FIG. 1, the RIP Input Server interacts with the RIP Advertisement Database Server so that it provides the relevant promotional information about Larry's Market to Greg by forwarding the information to Greg's email address, so that Greg can use the obtained information to receive a discount or obtain another benefit.

In FIG. 4, the caller user is not a registered RIP system user, similarly to FIG. 2, but in this example is calling in response to an advertisement in print media.

In particular, in this example, Greg sees an advertisement in the print media for a good or service he is interested in.

Greg dials a phone number provided by the RIP system that could be mentioned in the advertising or otherwise known to Greg, and says an expression corresponding to the advertisement (e.g., “Larry's Market”). The RIP Input Server recognizes the expression provided by Greg, but doesn't recognize Greg as a registered user. Therefore, the RIP Input Server tells Greg to visit an indicated electronic location (e.g., a particular indicated part of a Web site) to retrieve the relevant information, in a manner similar to that described with respect to FIG. 2. The RIP Input Server then interacts with the RIP Advertisement Server so that it makes the relevant information available to Greg at an indicated electronic location in a manner similar to that described with respect to FIG. 2, and Greg accesses the indicated electronic location to obtain the relevant information.

In FIG. 5, the caller user is a registered RIP system user, similarly to FIGS. 1 and 3, but in this example is leaving himself a voice memo to provide a reminder of a later action to take. While the user is not calling to request particular information, the RIP system nonetheless automatically determines relevant information for the user based on the voice-based information in the voice memo. In particular, in this example, the RIP system determines that an advertiser has previously selected an expression with which to associate a particular advertisement or other marketing information, and that the advertiser-selected expression is used by the user in his voice memo. Therefore, the RIP system automatically determines that the advertiser's marketing information is relevant for a current context of the user based on the inclusion of the expression in the user's voice memo, and includes the marketing information along with the voice memo when later providing the voice memo information to the user, or otherwise provides the marketing information to the user. The user can then optionally act upon the advertiser's offer if so desired.

In particular, in this example, Greg dials a phone number provided by the RIP system and leaves himself a voice memo, which in this example is “Buy Sam a bicycle”.

RIP Input Server sends this message over to RIP Advertisement Database Server, which analyzes the voice-based information to identify if there are one or more expressions included in the message that correspond to advertiser-selected expressions or that otherwise indicate context information for the user for which relevant information may be identified. In this example, the RIP Advertisement Database Server determines that the expression “bicycle” is an advertiser-selected expression that Huffy Bicycles Inc. has purchased for use with the RIP system. The RIP Advertisement Database Server then sends Greg an email to his registered address with the memo (e.g., as an audio attachment, as text generated by an automated speech-to-text conversion, etc.), as well as with the marketing information specified by Huffy Bicycles Inc. for the “bicycle” expression.

In FIG. 6, the caller user is not a registered RIP system user, similarly to FIGS. 2 and 4, so the RIP system knows at most the number of the phone originating the call, unless the user is prompted to provide identifying information during the call. In this example, the RIP system provides functionality similar to that of directory assistance and/or enhanced directory assistance, so that users may call the RIP system to obtain relevant information of various types. The RIP system may provide relevant information to a caller user in a substantially immediate manner, such as via the same phone call, via a text message or other electronic message to the device used to make the call, via an electronic message to an electronic message address designated by the user, etc.

In particular, in this example, Greg dials a phone number provided by the RIP system, says the expression “Dry Cleaning 98005”, and ends the phone call.

In response, the RIP Input Server sends this message over to RIP Advertisement Database Server, which analyzes the voice-based information to identify one or more expressions included in the message. The RIP Advertisement Database Server determines that there are several businesses matching the keywords “Dry Cleaning” and “98005”, such as businesses that have previously registered with the RIP system or whose information is otherwise available to the RIP system, and also determines that there are discount coupons associated with a couple of them. In this example, the RIP system sends one or more text messages to Greg's voice device with all the known matches for “Dry Cleaning & 98005”, as well as the coupons, although in other situations may send different types of information and/or in a different manner.

In addition, the RIP system may provide various other types of functionality in other embodiments. As one example, advertisements for homes may each include a unique code (e.g., a number, alphanumeric code, etc.) or other expression, and after calling the RIP system and saying the unique expression for a particular house, a user may receive an email with details about that particular house. Similarly, advertisements for new and/or used cars may similarly include unique expressions for each car, and the RIP system may similarly provide details about a particular car to a user after the user calls the RIP system and supplies the unique expression for the car. In addition, a business may create an in-store promotion for particular coupons or other types of information, which may similarly be accessed from the RIP system using unique codes or other expressions. It will be appreciated that the RIP system may similarly provide information for a wide variety of other goods and services.

In some embodiments, the RIP system may operate an advertisement database and a business-to-business commerce engine, allowing businesses to bid on keywords or other expressions with which they would like to associate particular promotional information. For example, businesses may supplement standard directory services information to indicate their relevance to particular expressions and/or to provide additional promotional information, such as by bidding on expressions that are relevant to their business. As one example, Bakkers Drycleaners may bid for “Dry Cleaning” and “98005”, so that the business matches all queries that include both (or alternatively one) such expressions. In addition, businesses may specify information to provide to users based on their voice memos to themselves and/or others, such as by similarly indicating particular expressions with which to associate promotional information. In this manner, businesses may associate themselves with expressions other than zip codes and business categories, including expressions that are more general and/or more specific. As one particular example, a retailer may bid for words such as “book”, “toys”, “music”, “Sedaris” (for author David Sedaris), or “P9047” (for promotion P9047). Furthermore, businesses may associate themselves with expressions based on telephone area code locations, such that a local business might be interested only if calls originate from area code 425 rather than area code 415. Alternatively, even a nationwide business may wish to offer special deals in its branches in a particular location, such as if Pizza Hut desires to offer a particular pizza special on calls for expression “pizza” that come from area code 425. In some embodiments, when businesses or other entities specify particular expressions of interest, they may further specify other criteria related to when their promotional information should be provided for those expressions (e.g., only with users' voice memos to themselves, only at certain days/times, only for registered users whose demographic information matches specified information, etc.), while in other embodiments the RIP system may determine to provide such promotional information for any use of a specified expression or more selectively as determined by the RIP system.

FIGS. 7 and 8A-8B are block diagrams illustrating portions of an embodiment of a RIP system. In particular, FIG. 7 illustrates a high-level overview of an embodiment of the RIP system, FIG. 8A illustrates additional details regarding an embodiment of a RIP Input Server component of the RIP system, and FIG. 8B illustrates additional details regarding an embodiment of a RIP Advertising Database Server component of the RIP system.

FIG. 7 is a block diagram illustrating example computing systems suitable for performing techniques for providing contextually relevant information based on voice-based information in various situations. In particular, FIG. 7 illustrates a server computing system 700 suitable for executing an embodiment of the RIP system 740, as well as various client devices 750 and 770 for interacting with the RIP system, and other computing systems 790 (e.g., systems that may have relevant information available to the RIP system, such as directory information). In the illustrated embodiment, the client devices include telephone-based devices 750 and computing devices 770, such as to allow users to access functionality from the RIP system and to allow advertisers and other entities to specify promotional information corresponding to particular expressions. In some embodiments, at least some devices may have capabilities to act as both devices 750 and 770 (e.g., cell phones that have both voice-based and data-based data retrieval capabilities, computing systems that include microphones and speakers and other components to enable Internet-based or other types of telephone calls to be placed, etc.).

In addition, in this example embodiment, the server computing system 700 has components that include a CPU 705, storage 720, and memory 730, and various I/O components 710, including a display 711, a network connection 712, a computer-readable media drive 713, and other I/O devices 715 (e.g., ports or other connections for one or more incoming telephone lines, a microphone, a speaker, a mouse, keyboard, etc.). The storage 720 includes a database 725 to store various information, such as information about registered users, information about advertisers and other entities who provide promotional information, the promotional information, directory assistance and other relevant information for users, various voice memos and other input supplied by users, etc. Furthermore, in some embodiments, various specialized hardware and/or software components may be included, such as to perform automated speech-to-text and/or text-to-speech conversion. The other devices and systems 750, 770 and 790 each may include similar components to those of the server computing system, but are not illustrated in detail here. Similarly, while not illustrated in FIGS. 8A and 8B, the RIP Input Server component and RIP Advertising Database Server component may each be provided by one or more distinct computing systems (or by a single computing system that provides both), and each such computing system may similarly include various such components.

As noted, an embodiment of an RIP system 740 is executing in memory 730, so as to interact with the client device 750 and 770 over one or more networks 780 (e.g., one or more landline telephone networks, one or more cellular telephone networks, the Internet, etc.) using the network connection 712. In the illustrated embodiment, the RIP system 740 includes an RIP Input Server component 742 and an RIP Advertising Database Server 744, as described in greater detail in FIGS. 8A and 8B. In addition, one or more other programs 735 may optionally be present and executing in memory 730, such as to provide other related functionality (e.g., to obtain payments from advertisers and other entities, to register new users, to provide functionality for advertisers and other entities to bid on keywords and other expressions or otherwise specify promotional information for expressions, etc.). In this embodiment, the RIP system is implemented in part or in whole in software, such as via one or more software components with executable software instructions that are stored in the memory 730 of the server 700 for execution and/or on storage 720 of the server 720.

FIG. 8A illustrates additional details with respect to one example embodiment of a RIP Input Server component 742, which has several sub-components in the example embodiment, as follows:

A Voice Connections Manager component 2, which manages voice connections from external voice sources to the RIP Input Server, including voice input 1 from calls for users (e.g., via landline phone devices, mobile phone devices, other desktop voice input devices, etc.). The Voice Connections Manager component 2 may accept connections in various ways, such as by using standard SS7 (Signaling System 7) signaling and/or Voice over Internet Protocol (using Session Initiation Protocol and similar other technologies), maintains voice calls until the users have completed their interactions, and also obtains and stores caller identification information in at least some embodiments.

A Speech Recognizer component 3, which accepts user voice-based speech input and converts it into text, such as via speech-to-text translation and/or by using human transcriptions. In at least some embodiments, it converts speech into text in a substantially immediate manner (e.g., within a second), or may instead take longer (e.g., a few minutes, hours or days). The Speech Recognizer component 3 may also provide responses back to a user caller through the Voice Connections Manager component 2 in some embodiments, such as to interactively provide information (e.g., promotional information) to the user (e.g., via automatic text-to-speech conversion, or via use of promotional information in recorded audio form).

A Subscriber Database component 4, which contains details of registered users of the RIP system in the illustrated embodiment, such as to store a registered user's email addresses, phone numbers, instant messaging addresses, phone providers and preferences. Various other types of user-specific information may similarly be stored and used in other embodiments.

A Work Item Queue component 5 for use in providing information about interactions with users to the RIP Advertisement Database Server so that the RIP Advertisement Database Server can perform further functionality of the RIP system corresponding to those interactions, although in other embodiments a single server system may provide functionality of both the RIP Input Server and the RIP Advertisement Database Server. In this example embodiment, some or all user interactions with the RIP Input Server will be sent to the RIP Advertisement Database Server in a reliable fashion using the Work Item Queue component 5, which ensures that an item has been accepted by another component before deleting the item from the queue. In some embodiments, the Work Item Queue component 5 may further accept work items to be handled by the RIP Input Server, such as from the RIP Advertising Database Server.

FIG. 8B illustrates additional details with respect to one example embodiment of a RIP Advertising Database Server component 744, which has several sub-components in the example embodiment, as follows:

A Work Item Queue component 1 for use in obtaining information about interactions with users from the RIP Input Server so that the RIP Advertisement Database Server can perform further functionality of the RIP system corresponding to those interactions. In particular, in this illustrated embodiment, some or all user interactions are each encapsulated as a separate work item that may be exchanged between various components. In some embodiments, the Work Item Queue component 1 may further be used for reliably sending work items to other components, including the RIP Input Server.

An Advertisement Database component 2 for use in storing marketing and other promotional information for advertisers and other entities, as well as corresponding keywords and other expressions for the promotional information (e.g., expressions that are purchased or otherwise selected by the entities). Types of expressions associated with promotional material may vary in various embodiments so as to include words and phrases at varying levels of specificity and of various types.

A User Network Interface component 3 for use in providing information to users over one or more networks, such as over the Internet and/or over a voice-based telephone network. In the illustrated embodiment, both registered and unregistered users may access information of various types, such as a voice memo that they previously saved (or was saved for them by someone else) or promotional information that they requested or that was otherwise automatically determined to be relevant for them. In some embodiments, some or all information may be provided to at least some types of users (e.g., registered users, all users, etc.) in other ways, such as via one or more electronic messages sent to the users.

A Notification Service component 4 for determining relevant information for users, such as by matching expressions in user speech input (e.g., voice memos, requests for additional information corresponding to advertisements or for directory services information, etc.) to content in the advertising database.

One or more client data devices 5, such as desktop computers, for use by users in accessing information from the RIP system via the User Network Interface component 3 over a data network. For example, a client device 5 may be a standard desktop computer executing any operating system and Web browser, and optionally including a voice interface and/or executing one or more instant messaging clients.

One or more client phone devices 6 for use by users in accessing information from the RIP system via the User Network Interface component 3 over a phone network. For example, a client phone device may be a landline or mobile phone that can receive voice signaling and content, and optionally text messages.

FIG. 15 illustrates a flow diagram of an example embodiment of a Relevant Information Provider system routine 1500. The routine may be provided by, for example, execution of an embodiment of the RIP system, as described in greater detail elsewhere.

The routine begins at step 1505, where an indication is received of input to the routine, such as voice-based input from a user, an interaction with an advertiser or other entity to provide promotional material, or other type of interaction. The routine continues to step 1510 to determine if voice-based input is received from a user (e.g., a voice memo, a request for particular information, etc.), and if so continues to step 1515 to analyze the voice-based input to attempt to identify one or more expressions that correspond to relevant available information. In some embodiments, the routine may further attempt to identify whether the user is a registered user, or to otherwise gather information from the user (if step 1515 occurs as part of an interactive connection with the user, rather than the processing of previously received voice-based input) related to providing relevant information to the user. In step 1520, the routine then attempts to retrieve one or more pieces of relevant information (e.g., one or more pieces of promotional information from one or more advertisers) that correspond to each of the expressions identified in step 1515, and in step 1525 optionally performs additional handling of the received voice-based input (e.g., to store a voice memo for later retrieval by a user, to automatically transcribe a voice-based memo to text, etc.). In step 1530, the routine then provides any retrieved relevant information to the user and/or one or more other recipients of the voice-based input (e.g., during a telephone call in which the voice-based input was received, by sending one or more electronic messages, by storing the information in a network-accessible location and providing access information for that location to the user, etc.), and optionally also provides information corresponding to the voice-based input (e.g., a text transcription).

If it was instead determined in step 1510 that voice-based input from a user was not received, the routine continues instead to step 1540 to determine whether promotional or other potentially relevant information was received in step 1505 from an advertiser or other entity, and if so continues to step 1545 to store or otherwise handle the information for later use. After step 1545, the routine in this example embodiment continues to step 1550 to optionally receive payment (e.g., corresponding to a one-time fee, or a pre-payment on later fees to be accrued) or payment information corresponding to the provided information. While not illustrated here, in at least some embodiments and situations, entities may be charged for some or all instances in which their provided information is provided to a user, such as to correspond to a form of pay-per-call advertising.

If it was instead determined in step 1540 that promotional or other potentially relevant information was received in step 1505, the routine continues to step 1560 to perform one or more other indicated actions as appropriate (e.g., related to registering users; registering advertisers and other entities; providing access to users and/or entities about prior interactions with the RIP system, including access to voice memos; etc.). After steps 1530, 1550, or 1560, the routine continues to step 1595 to determine whether to continues. If so, the routine returns to step 1505, and if not continues to step 1599 and ends.

FIGS. 9-14 illustrate examples of information flow that may occur in some embodiments, and in particular to correspond to the example scenarios of FIGS. 1-6.

FIG. 9 illustrates an example information flow that corresponds to Scenario 1 illustrated in FIG. 1. In that scenario, a registered user is reacting to an advertisement in a broadcast medium such as radio or television (e.g., over airwaves, Internet-based, satellite-based, etc.). In this example, the flow is as follows:

1. After the user sees the advertisement, the user contacts the RIP system, such as by calling an appropriate telephone number, or in other embodiments by using a URL (“Uniform Resource Locator”) or other URI (“Uniform Resource Identifier”). As one illustrative example, a user may contact the RIP system using a connection based on an SIP (“Session Initiation Protocol”) URI, such as over a voice connection initiated by placing a telephone call using an SIP URI “phone number” (e.g., sip:<username>@<host>:port, where <username> is replaced by an actual username and <host> is replaced by a domain name or IP address, such as john.smith@212.111.1.111 or support@abcdefgh.com), as described in greater detail in the RFC 3261 standard.

2. The RIP Input Server accepts the call and creates a corresponding session. It also checks if the caller ID number (e.g., “4255550154”) maps to a registered user. If it does, as in this case by mapping the caller ID to user Greg, it associates the session with this information.

3. The user says the expression “Larry's Market” as prompted by the advertisement.

4. The RIP Input Server recognizes the expression “Larry's Market”, and in the illustrated embodiment indicates to the user that it recognized the expression.
